TURNER H. LANE, OF MEMPHIS, TENNESSEE, ASSIGNOR OF ONE-HALF OF HIS RIGHT TO PHILIP A.

CHAMBER-MUFFLER.

BITTER, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 228,539, dated June 8, 1880.

Application filed March 31, 1880.

To all whom it may concern:

Be it known that I, TURNER H. LANE, of the taxing district formerly known as the city of Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Ohamber-h Iufller. of which the following is a specification.

The objectsof my invention are, first, to afford a simple, convenient, and useful device to to prevent the rattling sound in placing on the cover of the chamber, rendering the breaking of niches in edge of chamber impossible, and by covering the edge of chamber preventing scratching or cutting the skin in sitting on chamber; secondly, being made of india-rubber, or furfleeced, or felted with woolen, silken, cotton, linen, or any other wearing material, preventing the chilly sensation in handling chamber or sitting on its bare edge, thereby 2o obviating the necessity of warming it for the use of invalids or sick persons; thirdly, it prevents the escape of offensive odors and poisonous gases between the cover and rim of chamber, the pressure of the cover sealing the contents and preserving the atmosphere in close rooms and sleepingapartments from malaria arising from open or half-closed chambers. Figure l is a perspective view, and Fig. 2 is a sectional view of the muffler on line cm, Fig. I.

My invention consists of an elastic indiarubber ring, A, fleeeed or felted on its top or upper surface, which will expand and contract,

(No model.)

so as to fit tightly and firmly around the edge or rim of the largest or smallest sized chamber B, and while contracting sufficiently to remain adhering to the rim of chamber, yet is so pliant as to admit ofbeing easily removed by a slight movement of the hand whenever it may be necessary to empty contents ofch amber, thereby avoiding being soiled by coming into contact with the contents. The plan whereby I propose making said rubber ring or chambermuffler is half-ovaled, with handle-shield D, attached to ring or rim, which extends over rim or mold inside and outside the width of 5 any molded rim or ed of chamber, or to entirely em'elop edge or rim with muffler, if I so desire, material to be india-rubber or guttaperch a backing, with wool, silk, cotton, or linen facing or fleecing, (or any other soft non-nietallic substance,) in variegated or solid colors.

YVhat I claim as new, and desire to secure by Letters Patent, is-

1. A flexible chamber-muffler provided with a facing of felt, fleece, or fur, and adapted to be attached to the rim of a chamber, substantially as described.

2. A flexible chamber muffler; adapted to cover the rim of a chamber, and provided with a handle-guard, substantially as set forth.

TURNER H. LANE.
